CDO

Hello,

I'm using yearmonmean with my model data and it works but I always get an extra time index (i.e. months/12 +1 )

My monthly time variables look like
time = 730031, 730059, 730090, 730120, 730151, 730181, 730212, 730243,
730273, 730304, 730334, 730365 ;

but they are monthly averages with the last day indicating the month.

So I assume it is averaging according to the first 11 months, then the last month for a 2 year timeseries?
Is this correct?
Do I need to re-index my netCDF time variable?

Thanks
Guido
